MACHINE FOR IMPBEGNATING MATCH-STICKS.

have invented a certain new and useful lime provement in Machines for Tmpregnating Match-Sticks, of which the following is a full, clear, and exact description.

The object of this invention is to provide means for the ready and eflective impregnation of match sticks with a vehicle which will prevent after-glow and so reduce if not eliminate fire-danger in the careless handling of lighted matches. 1 The invention consists of mechanism for applying the impregnating material in the form of dust or fine powder, under conditions which will cause it to adhere to the sticks.

Tn the preferred construction this mechanism will form a part of a continuous match machine, in which the operations of cutting, sticking, impregnating, paraffining, dipping anddrying are successively carried on, and wewlll so show and explain our invention herein, but withoutthereby limiting the invention to any particular ma-.

chine or tea match machine.

In the accompanying drawings illustratwhich like parts are similarly designated, Figure l is a transverse section and partial ing mechanism hen forming part of a cdntinuous match machine; Fig. 2 is a longitudinal section with the cover omitted. Figs. 3 and a, 5 and and 9 and 10 are respectively elevations and edge views of four several forms of blades for circulating the impreg nating material and insuring its application to the sticks.

When used in and as apart of a continuous match machine, theim regnating machine may utilize the side rames 1 of the machine for the reception of its-component parts, and these side frames may be connected by four converging sloping walls, as shown in Figs. 1 and 2, so as to form a bin 2 to receive the impregnating vehicle in the formof finely divided powder or dust. suitable impregnating material or vehicle is ammonium phosphate, reduced to an impalpable powder or dust, but the invention Specification of 'Letters Patent.

is not limited to the use of any particular lmpregnating agent.

Inclined shafts 3 are arranged trans- ,versely of the frame within the bin, and

these shafts. are supported in suitable bearings 4 in the frame, and other bearings 5 in the bin, and on these shafts and turning with them are paddle wheels or agitators 6 which serve to stir up the material in the bin. .These agitators are rotated from a power shaft 7 mounted in the frame and supplied with any suitable pulley or other power-receiving agent 8, and transmitting motlon to the shafts 3 by any suitable means,

such as bevel gears 9 and 10. Abovethe agitators are shafts 11 and 12, also arranged transversely of the machine, and having bearings in the side frames and arranged parallel one to the other. These shafts 11 and 12 are provided with blades 13 suitably spaced'apart by "washers 14. 'These' blades any of a variety of different forms, some of which are illustrated in Figs. 3 to 10, thefunction of which blades is to throw the impregnating material upon the match sticks.

The shafts l1 and 12 are geared by toothed wheels 15 so as to turn in opposite directions, and they are rotated by means of a toothed wheel 16 on one of the shafts engaging a toothed wheel 17 on the power shaft. These shafts, 11 and 12 may also be given a slight longitudinal vibratory movement by 18 engaged by rollers 19 fixed to the side frames. The side frames ways 20 to receive and guide thesplint-carrier chains or plates 21 in which the match sticks 22 are stuck.

. These match sticks extend downwardlybetween adjacent blades 13, as indicated in Fig. 1.

23 is a cover (Fig. 1) bin and the splint carrier cape of the air and dust or powder from within the bin. Mounted upon the side frames are the hoppers 24: which extend down into the bin and serve as means forintroducing the dust or powder within the bin. The bin having been supplied with the impregnating material, and the carrier supplied with match sticks, and moved over the bin, the rotation of the agitators 6 will raise a cloud of dust or powder to the rotating blades 13 and these splint arranged over the to prevent the esthence to the bin, where it is eralprojection of will distribute the dust about the sticks with force enough to cause it to adhere to the sticks with suflicient tenacity to thoroughly impregnate the sticks, and without danger of the sticks losing the impregnating material in their further progress through the match machine, or their further treatment otherwise. v

' As already indicated, the blades 13 may be of a variety of forms. Referring to Figs. 3 and 4, the blade'is shown in the form of a conventional Maltese cross, the opposite edges 25 of its arms 26 being drawn to a point, as indicated in the end view developed off of one arm above and to the left in Fig. ,3, and also as shown in Fig. 4. As shown in-Figs. 5 and 6 the blade may be made as bl with diagonally arranged holes 27. As shown in Figs. 7 and 8 the blade may be cruciform. In this case each arm 28 may have one of its edges 29 grooved and flared, and its opposite edge 30 beveled. As shown in Figs. 9 and 10 the blade may provided with strips of. bristles or fine wires 31 fastened thereon or therein, so as to project laterally preferably from both sides. In all of these forms of blades the tendency is todirect the current of dust against the rows of match sticks, and in addition the strips of bristles or fine wire shown in the construction illustrated in Figs. 9 and 10 will whip against the match sticks and tend to polish the match sticks. Furthermore, all of these various'forms of blades effectively circulate the dust constantly and uniformly among the sticks as the sticks pass through the dust chamber and between the blades. The beveling of the arms of the blades as shown in Figs. '3 and, 4 and the diagonal holes, shown in the blades of Figs. 5 and 6, and the flaring and beveling of the arms as shown in Figs. .7 and 8, and the latshown 1n Figs. 9 and 10 insure the distribution of the dust against the match sticks, and as already stated, insure its constant circulation. If desired, and in orderlonger to expose the match sticks to the dust, the dust chamber above the bin may be extended in front and rear of the bin as indicated in Fig. 2.

The operation of sufliciently indicated it is sufiicient now to nating powder is fed the machine has been inv what precedes, and state that to the hoppers 24 and agitators 6 which in their rotation st1r up the dust in a cloud-like form. This cloud of dust is then circulated between the depending match sticks 22 by means of the rapidly rotating blades 13, and by rotating the blades on opposite shafts toward one another the circulation of the dust is'directed in such a manner that the dust will impinge directly on both the front and rear of the time the preferred, construction be a disk,

non-glowing.

bristles or wires as the impreg-,

match sticks as the sticks are moved through the machine and between the blades.

We have thus described one, and at this illustrating our invention, but esteem it as within our invention to modify the parts and their arrangement within the scope of the following c aims.

What we claim is '1. A machine for impregnating match sticks, so as to render them non-glowing, comprising a bin, means to supply it with pulverulent impregnating material, rotary agitators arranged at or near the bottom of the bin, a pair of oppositely rotating shafts mounted above the agitators, distributing ades mounted on said pair of shafts and spaced apart thereon, and means to permit the conveying of the match sticks across the bin in ordered relation so that said sticks will pass between the spaced apart blades, said blades serving to direct currents of the impregnating material toward the sticks and cause such material to-adhere to the sticks.
